Pulsation theory of ascent of sap was proposed by

Options

A. Dixon and Jolly
B. J.C.Bose
C. Curtis and Clarke
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the scientist who proposed the pulsation theory of ascent of sap.

2. **Identifying the Theory**: The pulsation theory explains the mechanism of how sap (water and minerals) ascends through the xylem tissue in plants.

3. **Recalling Key Information**: The theory suggests that electrical pulses created in living cells lead to the movement of sap through the xylem.

4. **Identifying the Scientist**: The scientist who proposed this theory is Jagdish Chandra Bose, often abbreviated as J.C. Bose.

5. **Historical Context**: This theory was proposed in the year 1927, highlighting the significance of electrical activity in the ascent of sap.

6. **Conclusion**: Therefore, the correct answer to the question is Jagdish Chandra Bose.

**Final Answer**: The pulsation theory of ascent of sap was proposed by Jagdish Chandra Bose.
